Abstract

We developed a non-contact and non-destructive method to detect Curie point (T_C) in Er³⁺doped Ba_0.77Ca_0.23TiO₃(BCT) ferroelectric ceramic. Through investigating the photoluminescence (PL) spectra of Er³⁺doped BCT ceramic we found that PL characteristics in ferroelectrics demonstrates critical behavior around T_C. Both intensity and peak positions of the Stark sub-peaks originating from⁴S_3/2to⁴I_15/2transition change dramatically, and can be fitted with two different lines below and above T_C. The inflection points of the PL characteristics are at the same temperature of 381(1) K, and coincident with the T_C(381 K) determined by the dielectric temperature spectrum.
